Re: [Elecraft] [K3] K3 RX Equaliser SW App?
Doug, I didn't see the start of this thread, so I'm not sure what you're seeking, but have a look at K3_EZ at: http://home.roadrunner.com/~n2bc/SW.htm All sorts of things you can set with it, including the equalizeers. 73, Mike NF4L GM0ELP wrote: > Hi Paul, > > Yes, I would also like to see firmware RX EQ by mode, but I've been told > it's a long way down the Elecraft to-do list due to complexity.

Re: [Elecraft] [K3] K3 RX Equaliser SW App?
Hi Paul, The rest of my post gave reasons why K3-EZ isn't the right solution for me, but thanks for the suggestion. In reading the content of the K3-EZ link you gave, it says that K3-EZ doesn't work with LP-Bridge. This is also a bit of a show stopper for me as my logging and pan adapter software are normally running on my PC.

Re: [Elecraft] [K3] K3 RX Equaliser SW App?
Hi Paul, Yes, I would also like to see firmware RX EQ by mode, but I've been told it's a long way down the Elecraft to-do list due to complexity. However a software approach opens new possibilities limited only by the CAT port speed. By AF I mean the 50,100,200,400,800,1600,2400,3200Hz bands in the RX EQ menu. I would like software to remove the manual drudgery (speed up operation) of me having to manipulate an 8 band graphic equaliser for common AF responses i.e. peak and notch check boxes and a sliders for width, ref level, magnitude and frequency. I suppose the usefulness of any such software calls into question the usefulness of the RX Equaliser in general.

Re: [Elecraft] [K3] K3 RX Equaliser SW App?
Hi Paul, The bandwidth and Notch should be done at the IF stage not the AF stage, I think everyone knows this. There has never been a question of where it is better to taylor response. Of course it's better to do these things at the IF stage. I am suggesting a 'cumulative' IF and AF response 'combined'. I could manually taylor (approximate) any required AF response using CAT commands and the available 8 audio bands and gain/attenuation levels. Why wouldn't software be able to do that? It's not a question of how steep the slopes are, its a matter of using an AF feature in the K3 to augment the IF performance. If there was a software tool available to approximately track AF to IF response would you try it? I would, and I think it is possible. Can you give me a reason why it isn't possible?

Hi Doug, Some time ago Wayne and Lyle explained that the RX EQ is not meant as an extra "selectivity tool". It's there to do the last tailoring of passpand response, make up for room acoustics or speaker/hp response. The RX EQ modifies the IF passband and is not a seperate post-detector AF filter.

Ideally I would like something that replaces the manual manipulation of individual graphic equaliser sliders with more automated/general filter creation controls i.e. lpf/hpf(buttons), cuf-off freq (text entry box), peak/notch (buttons), magnitude and sweep (sliders). I don't have a specific use in mind, other than to be able to use the rx equaliser whilst operating.

That is the only way to read or change the EQ settings at the moment and that is not a good thing to be doing while logging, panadapter and other software is running due to a potential conflict with the up / down commands used to change the menu settings. So the short answer to your original question is no, such an application does not exist because the K3 does not support a way to get / set the EQ settings that can safely be used during normal operation. - Julian, G4ILO.

The RxEQ is applied to the *AF* filter, which also implements low pass, manuall noth, etc. The SHIFT and WIDTH controls apply to both an IF and an AF filter. Thus, the RxEQ is not an additional filter cascaded with other audio filters, but is part of the description of the desired filter being fed to the filter design routine in the DSP firmware running in the K3. 73, Lyle KK7P/7 (Arizona) __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] [K3] K3 RX Equaliser SW App?
Hi Doug, I never say something can't be done ;-) There only is no seperate AF EQ in the K3. The RX EQ is directly modifying the IF response, in other words RX EQ acts directly at the DSP IF filter stage, that is the way Lyle designed it. The data of both IF slope and RX EQ are combined to a single IF passband calculation. In that sense the RX EQ is no "extra filter"... So f.i., if you design a certain steep HPF with the RX EQ you are in fact doing exactly the same thing as turning down the low flank in IF. I think that's why Lyle&wayne advised not to use the RX EQ for such goals. It would be nice though to have a "library" of EQ settings, but I personally would prefer that in the K3 itself (EQ per mode, bypass on/off switch, EQ preset memory) 73' Paul PD0PSB GM0ELP wrote: > > Hi Paul, > > The bandwidth and Notch should be done at the IF stage not the AF stage, I > think everyone knows this.
